COMPUTER SECURITY SUBCOMMITTEE
OF THE
UNITED STATES INTELLIGENCE BOARD
SECURITY COMMITTEE
IBSEC-CSS-R-7
19 February 1971
MEMORANDUM FOR: Chairman, United States Intelligence
Board, Security Committee
SUBJECT Security Responsibilities in Interagency
Computer Terminal Links
1. In recent months, an increasing number of remote
terminal installations have been identified where the terminal
device is located in one agency of the Community and is linked
to the computer system of another agency. Such installations
present possible jurisdictional conflicts with regard to the
responsibilities involved in the security of their operations.
The possible conflict arises from their operation in an on-line
mode when the security responsibilities of the two agencies are
not specifically defined.
2. The Computer Security Subcommittee has reviewed
this problem and feels that it may be addressed in generic
fashion by the establishment of basic U5IB policy for the security
responsibilities involved.
3. The Subcommittee has prepared the attached report
as a proposed statement of USIB policy for such interagency
computer terminal links.

to the Board for the latter's noting.

I. PURPOSE:
To establish USIB policy defining security responsibilities
in interagency computer terminal links.
II. DEFINITION:

terminal which is connected to the computer central processing
unit and thereby operates as a part of a computer system con-
trolled by a different USIB agency.
III. POLICY:
I:cl the operation of interagency computer terminal links,
the following security responsibilities are recognized:
A. Security requirements, including procedural
controls, for the operation of remote terminals will
be defined by the agency operating the central pro-
cessing unit to which the terminal is connected;
B. The agency installing and operating the remote
terminal will insure that all security requirements,
including procedural controls specified by the agency
operating the system, will be followed in its use of the
